At one point, after passing Bijan, “the most expensive store in the world,” (it costs $1,500 just to walk in the door), Sgroi thought she recognized someone on Rodeo. “Was that Diane Von Furstenberg?” she asked as the bus kept moving. “Does anyone know who she is?” (Blank stares).

The star-searching sagged. But avid TMZ fan Mario Luna, 32, gave the tour high marks for humor and noted Sgroi “pointed out so many spots I didn’t know about in L.A. and I live here.”

Even gridlocked traffic didn’t hinder the travelogue — to kill time, gossip groupies vied for TMZ T-shirts by guessing how Keanu Reeves and Emma Stone each reacted to being caught on TMZ tape. The game was titled “The Finger or The Wave.” Then, on to more dirty-laundry landmarks, including the Hustler erotica store where “Britney stole a pink wig during the bald era” and the In-N-Out Burger that Paris Hilton was rushing to when she got popped for DUI.
